Inventor: WILKS JOHN JAMES
IPC: G11B15/67
Filed: 1962-03-01
Abstract: 930,055. Control of A.C. motors. CREED & CO. Ltd. March 1, 1962, No. 8002/62. Class 38 (3). [Also in Groups XVI, XXXV and XXXVIII] A control circuit for the electric motors of a tape supply apparatus (see Group XVI), has an A.C. supply P connected to a rectifier REC and resistance R1 such that when contacts 26 and 25 are closed the stator ST is supplied with D.C. current and A.C. current when contacts 25 and 27 are closed. When a tape reader TR is started motor switch S is closed, thereby applying a braking action on the motor. Roller 22 causes cam-plate 18 to pivot clockwise to close contacts 25, 27 and remove the braking action.

Patent GB-143273-A (GB)
Title: An improved method of working apparatus for producing low vacuum in steam condensers
IPC: F01B25/00
Filed: 1916-06-10
Abstract: 143,273. Morison, D. B. June 10, 1916. Condenser systems. - In steam-condensing plant, the condenser a is evacuated by a steamjet air-ejector c in combination with a supplementary condenser r, which may serve as a feedheater, and an air-pump b or other air-discharging device, in such manner that the steam jet withdraws from the condenser substantially all the steam-air mixture the temperature of which would be, if it remained in the condenser, about or below the temperature of airless steam at the degree of vacuum prevailing in the zone of withdrawal. By this means the air-bed or " inactive " zone in the condenser is suppressed. A plant for withdrawing, in this manner, an amount of steam in excess of that ordinarily withdrawn comprises a condenser of reduced condensing-surface and a circulating-pump of reduced capacity, as compared' with present practice. The size of the plant is thus reduced, the power required to drive the circulating-pump is reduced, and the temperature of the condensate is increased. The plant may be arranged in the ordinary manner. It is preferred to use a wet-air pump b, e.g. an Edwards air-pump to which the air &c. is led by a pipe g, and the condensate bv a pipe d. The condensate normally flows to the air-pump b through a looped pipe f or water seal. By opening the valve e and closing the valve s, automatically or otherwise, the plant may be made to operate in the ordinary manner. The water used in the feed-heater r is condensate, derived by a pipe m from a compartment h on the discharge side of the air-pump. The heated water flows away through a seal n and then through pipes under the control of a valve p either into the upper part of the condenser or to the air-pump suction d. The water and the air &c. from the condenser f may also be led together through the same pipe to the pipe d. The condenser f may also be formed as a well on the pipe d, to which the steam is led by the means described in Specification 11690/10, [Class 64 (i), Heating liquids &c.], or as a receiver on the upper side of the pipe d, to which the whole of the condensate is led by an extension of the discharge end of the pipe f. The condenser f may also be integral with the air-pump, or the steam may be discharged direct to the suction receiver of the air-pump. The condenser a may be either a surface or a jet condenser.

Title: Improvements in and relating to stretching apparatus for fabric or other material capable of undergoing plastic deformation
Inventor: CZERNIN ALEXANDER FRIEDRICH
IPC: D06C3/00
Filed: 1960-03-10
Abstract: 904,386. Finishing fabrics. PASOLDS Ltd. March 2, 1961 [March 10, 1960], No. 8447/60. Class 42 (1). Apparatus for stretching fabric comprises two or more elements 1, 2 having ribs or other projections between which elements the fabric passes to be engaged and stretched thereby, the ribs or projections 3 being laterally spaced from one another and being disposed parallel to the direction in which the fabric is passed, the fabric being caused to pass between the spaces separating adjacent projections. In one embodiment, Fig. 2, metallic discs 3 are mounted on driven rollers 1, 2 which are adjustably mounted in a slide (not shown) so that the spacing of the horizontal roller axes and hence the degree of stretch imparted to the fabric may be varied. A freely rotatable feed roller 5 is provided. Tubular knitted fabric is preferably stretched after washing, the dampness of the fabric increasing the frictional resistance between the rollers and the fabric. In a modification, Fig. 3, the fabric passes between a driven, ribbed roller 9 and a ribbed reciprocating member 10. As the fabric passes over the roller 9 the member 10 moves downwardly and rearwardly, the rearward movement preventing the member 10 from moving relatively to the fabric whilst in contact therewith. A crank-wheel 16 drives the member 10 through the linkage shown. The rocking movement may be adjusted by moving the position of the crank-wheel 16 to vary the depth of engagement between the member 10 and the roller 9. In a modification, not shown, freely rotatable discs are mounted between the discs 3 on each roller and are spring- biased to nip the fabric between them and the discs on the other roller. In a further modification, the discs 3 are provided with radial needles to penetrate the fabric. In another modification, the fabric is stretched by passing it between two reciprocable comb-like elements.

The auxiliary turbine may drive a supercharger for raising the pressure of air entering the compresssor cylinder. One gas generator of the free-piston type may supply a number of auxiliary consumers. The dischargers from gas generators 1 flow through the delivery conduits 2 to auxiliary turbines 3, which extract some energy before discharging the gas through conduits 4 to the common manifold 5 and main turbine 6. Turbines 3 drive superchargers 7, which have air inlets 8.

Abstract: 494,667. Electric signalling systems. RICKETS, W. J., and RAWLINGS, A. L. March 25, 1937, No. 8775. [Class 40 (i)] [Also in Group XL] An apparatus for detecting and indicating the presence of objects, for example aircraft, and locating their directions by means of infra-red or other invisible radiation, comprises in combination, an optical system 1, Fig. 1, forming an image of a field upon an opaque screen 2 having a slit 3, means, for example a reflector 4, for throwing the radiation passing through the slit on to a radiation-sensitive system, for example an electron multiplier 5, means for moving said image and slotted screen relatively to each other, a cathode ray tube 11, means for causing the line of oscillation of the electron beam of the tube to be altered in unison with the alteration of the relative position of the slit and image, and means for causing a high frequency oscillation of the electron beam with an amplitude or intensity proportional to the total radiant energy passing through the slit at each of its positions as detected by the radiation-sensitive system, whereby the luminous image or graph formed on the screen of the cathode ray tube serves as an indication in linear or polar coordinates of the position and to some extent of the relative magnitude of the objects sighted. Fig. 4a shows graphs that would be produced in polar co-ordinates by two aeroplanes. The direction of the optical apparatus may be adjusted to bring a graph in the centre of the screen of the cathode ray tube and then points in the direction of the object producing the graph. In Fig. 1, the slotted screen 2 and the line of oscillation of the cathode ray tube are rotated in synchronism. In a modification the slotted screen and the line of oscillation of the tube are reciprocated. And in another modification, Fig. 3, the slotted screen 2a is fixed, the image is reciprocated relatively to the screen by an oscillating mirror 12, and the line of oscillation of the tube 11 is reciprocated in synchronism by means of a Wheatstone device 14. The radiation-sensitive system may include an amplifier so biassed that radiations below a certain strength do not affect the indicating apparatus. The potentials applied to the cathode ray tube for producing the graphs may be modulated unidirectional potentials.
